Be it known that L RUPERT ScIIULTIIEIss, a citizen ofthe UnitedStates ofAmerica, and-a resident -of Tacoma, in the county of Pierce and State ofWashington, have invented certain new and useful Improvements in Start.-ing-.Valves for Compound Locomotives, of which the following is aspecification. My invention relates to improvementsv in starting valvesfor compound locomotives adaptable to regulate induction and eduction ofmotive fluid, and has especial reference to a valve of this classadapted for embodiment with compound engines.

Among numerous objects attained by this invention is the production of abalanced rotary valve of simple kand inexpensive construction adaptableto either asingle or compound engine and readily adjustable at will torun a compound engine either simple,single, or normal;

The above-mentioned and other objects equally as desirable are attainedbythe constructions, combinations, and arrangement of parts, asdisclosed on the accompanying drawings, set forth in the followingspecification, and succinctly pointed out in the appended claims.

With reference to the drawings filed herewith and bearing like referencecharacters for' corresponding parts throughout, Figure 1 is a view of aportion'of the head end of a com` pound locomotive in front elevationand' shown with my improved valve embodied with `the motive cylindersthereof andone aside viewof the valve as preferably formed and indicatesthe seat thereof in longitudinall section online 3 of Fig. 4 and thevalve set to .operate a compound engine normal.

is a similar section to Fig. 4, taken on line 5 of Fig. 3 looking as thearro'wsindicate and shows the intercepting-shell set to operate acompound engine normal and the valve-plug midway its path of travel.Fig. 6 is a like sectionon line 6` of Fig. 3 viewed as the arrows liy,and Fig. 7 indicates alike view of the valve in transverse section online .7 ofV Fig. 3 looking as the arrows point. A n

This valve comprehendsa rotative cylindrical valve-plug, as 10,-arranged'to receive motive fluid interiorly and having suitable portsfor admission and distribution and a thereby conveniently arranged tolie free for independent movement in said seat, which isconveniently'formed in communication with suitable fluid-passagesleading to and from the engine-cylinders, as high and low lpressurecylinders, (marked a and b, respectively, inFig. .1 or o and CZ,respectively, in Fig. 2.) In the present embodiment valve-plug 10 isformed with both ends closed and with suitable partitions, as 9 and 9',Fig. 1, or 9, Fig. 2, arranged to .afford separated chambers in theval-ve,f;as'an induction-chamber 14, adapted to receive live Huidprimarily for distribution to thecylinderof a single engine or thehigh-prese sure cylinder of a compound engine; an inter- 1 mediatechamber 15, Fig. 1, or 15, Fig. 2,'to

receive the exhaust from ahigh-pressure cyl- Y inder or live fluidprimarilyfa'nd also inter.-

mixingly with said exhaust, if desired, for distribution therewith tothelow-pressure cylinder when the engine is operating compound or fordistribution'of` said live fluid alone to the low-pressure cylinder whenthe engine is operating simple, and anexhaust-chamber 16,

IOO

Fig. 1, or 16, Fig. 2, adapted to receiveuid exhausting from both oreither cylinder and to act secondary to either the induction-chamber 14or intermediate chamber 15, or both, as determined by the nature of theengine, whether single or compound, or by setting the intercepting-shellto operate compound engines normal or simple.

From lthe foregoing it Will be understood that the passages for motivefluid leading to and from the cylinder or cylinders of an engineincorporating my valve are arranged in conjunction with a seat, as 13,and in conformity with the ports and apertures as arranged,respectively, in the plug and shell of the valve in accordance with thenature of the engine. In the present instance induction-chamber 14 isarranged in one end of plug 10, and a transversely-disposed port 19 issuitably placed in 4 the Wall of said chamber, Fig. 4, so as to lieconstantly in communication with alive-fluid passage, as 2O, leadingfrom a source of supply to seat 13, and oppositely-disposed ports 22 areformed in said wall, so as to alternately and intermittently registerwith respective fluid-induction passages 20', which lead-from said seatto opposite ends of an engine-cylinder, as a high-pressure cylinder a orc, Figs. 1 and 2. Exhaust-passages 23 are arranged to leadA the Huidexhausting from respective ends of said cylinder back to valve-seat 13,and the plug and shell of the valve are suitably formed to direct thisiiuid to intermediate chamber 15, Fig. 1, or 15, Fig. 2, fordistribution for further use in the engine, or to chamber 16, Fig. 1, or16', Fig. 2, for exhaust, and thereby render it possible to operate theengine single.

In the preferred construction of the valveplug partition 9 is disposedtransversely thereof adjacent one end `to form induction-chamber 14 atthat extremity of the valve, and partition 9' is disposed longitudinallythe plug between said transverse partition and the opposite end, so asto form intermediate and exhaust chambers, as 15 and 16, respectively,Figs. 1, 3, 5, and 7, and intercepting-shell 12 is rendered of suitablelength to cover said plug over said chambers 15 and 16. In the Wall ofchamber 16 a suitable exhaust-port 35 is arranged, Fig. 7 and apertures,as 36,v are formed in the opposing Wall of shell 12 relatively theretoand in conformity With an exy periphery and adapted to bring saidapertures into communication With exhaust-passages 23, leading from thehigh-pressurefcylinder,when the shell isadj usted to run the enginesingle or simple, and ports 28 are arranged inthe wall of pluglO atsuitable points to alter-v Yand is arranged so as to register with onepassage 23 When the shell is properly adjusted to cause one of theapertures 26 to lie directly in line with the opposite passage 23, asindicated in Fig. 7, and ports 24 are formed in the Wall of plug 1() atsuitable points, so as to intermittently register with a respectiveaperture 26 or 26 and admit the. fiuid exhausting through passages 23 tochamber 15 for distribution and further use in the engine.

In the present instance live steam is admitted direct from the source ofsupply to intermediate chamber 15 through an aperture, as 30 or 31, Fig.5, formed in shell 12 at suitable points to register with a supplementallive-uid passage, as 29, When the shell lies in either of its adjustedpositions. These apertures are controlled by plug 10, in the wall ofwhich oppositely-disposed ports 28 are arranged to intermittently admitHuid to chamber 5 "rom respective passages 29 and 31 when either of saidapertures register therewith, and thereby render it possible todistribute said luid to the low-pressure cylinder When the engine isrunning either simple or compound. The fluid admitted to intermediatechamber 15 is conducted to the low-pressure cylinder by passages, as 34,Fig. 6, a1'- ranged in communication with respective ends of saidcylinder and with valve-seat 13, Fig. 6. Apertures, as 33, are formed inpairs at suitable points transversely the wall of shell 12, so as toregister with these passages 34 when said shell lies in either of itsadjusted positions, and ports 32 are formed at opposite points throughthe wall of plug 10 to intermittently release fluid through respectiveapertures 33, and thereby supply the low-pressure cylinder. From theforegoing it will be understood that when shell 12 is adjusted to runthe engine simple the exhaust from the high-pressure cylinder passesinto chamber 16 for final exhaust and only live Huid is admitted tointermediate chamber 15, which is then distributed to the low-pressurecylinder. Should, however, shell 12 be adjusted to run the enginenormal, the exhaust from the highpressure cylinder passes into theintermediate chamber 15, and live fluid is also admitted thereto fromsupplemental passages 29 and intermixes with said exhaust and passestherewith to the low-pressure cylinder, as heretofore set forth. Thelow-pressure cylinder exhausts through passages 39, Fig. 5, into chamber16, Whlch 1s constantly open to passage IOO IIO

27, as heretofore set forth.' Shell 12 is formed with apertures 38,arranged in rpairs in v'the wallatsuitable `points to'give saidpassages'I 39 a delivery-way through said shell at all times', andports, as 37,v are 'conveniently'provided=in'the wall ofplug 10 atsuitable oppo-I site points to intermittently registerwithrespectiveapertures 38 to give a free exhaust at proper times.

As now considered valve-plug 10 is operated by means'of a crank, as` 40,fixedto a'suitable stem of the plug and operably connected to anysuitable reversing-gear, and theinterceptingv-shell 12 isadjustedthrough the me#- dium of a similar 'crank 41, attached to thestem thereof and operably connected to any suitable mechanism forturning the shell as desired to vary the application of motive fluid.y

I t will beunderstood that 'the several pas sages, apertures. and ports'are arranged in' relative positions in conformity with the length ofadjustmentof. the shell vand travel of theplug and" that thelvalveispractically balanced at all times owing to the passage ofthe motivefluid therethrough; furthermore, that the valve can be formed withoutthe'referencey to the'I supplemental passage 29, and thereby made tooperate an engine single, or it can be arranged to distribute Huid fromsaid passage haustfrom cylinder a, Fig. 1, passes through passages23,Fig. 7', to apertures 26, respec-V tively, and is admittedto'e'xhaust-chamber `16 through ports 28. When it is desired to run theengine normal, shell 12 is set to register aperture-26' with onepassage' 23, Fig.7, and 1 thus cause the fluid'exhausting from saidcylinder-"tol pass into intermediate chamber '15 through ports 24:,'andisdistributed to they low-pressure cylinder through ports 32, Fig. 6,apertures 33,v andpassages 34., and said cylinder exhausts to chamber 16through pas-4 sages'39, Fig.' V5, apertures 38, and ports 37.. Ifthevalve is arranged to admit fluid fromy passage 29 when'shel-l 12'isIadjusted to runa compound engine normal, the said fluid will enter'intermediate chamber lthrough aperture 31 and ports 28', Fig. 5, andthence Apass to the low-pressure cylinder, as heretofore set forth. Ifthevalve is arranged to admit said fluid t'o the intermediate chamberonly when the shell is adjusted to operate a compound" engine simple,the aperture 31 is omitted, andM the fluid will only be admitted throughsaid communication withy passage 29.
